the only problem I had was that it would maintain one ultrapeer connection and then also two .4 protocol connections as well. My connection traffic was high as my modem light was constantly going off. I was able to disconnect from the .4 protocol hosts and then get three ultrapeers, but it would crash constantly while doing this. I think that if you are a leaf, .4 connections should be dropped and the program should continue searching until it can find the three ultrapeers. Also, the speed on Mac OS X is GREATLY improved. Thanks for the hardwork. My six bucks is on the way.
